To @ZZ wil/mn it 11m/y concern:

Be it known that I, STEVEN ELMER GUT- RIDGE, a citizen of the UnitedStates, residing at Newark, in the county of Licking and State of Ohio,have invented a new and useful Ealing-Press, of which the following is aspecification.

This invention relates to baling presses, and has for its principalobject to provide a press of simple and compact construction in whichthe power employed in forcing the plunger during the compressionmovement may be gradually increased in order to compensate for thegradual increase in the resistance of the hay as the latter becomes moreand more compact.

A further object of the invention is to provide a novel form ofplungeroperating mechanism in which toggle levers are used to force the plungerforward, and in which the toggle operating mechanism is so arranged asto gradually increase the force exerted during the compression movementof the plunger.

A still further object of the invention is to provide a plungeroperating mechanism including a toggle lever, and means forautomatically shifting the point at which power is applied to the togglelever, so that increased leverage may be obtained during the compressionmovement.

A still further object of the invention is to provide a novel form ofpower head and mechanism for transmitting movement therefrom to theplunger, all ofthe mechan- .ism being arranged with a view of graduallyincreasing the leverage force exerted towardtheend ofthe compressionmovement.

A still further object of the invention is to provide a novel form offolder for co-operation with the plunger in feeding the hay from thehopper section into the baling chamber proper.

A still further object of the invention is to provide a hay folder orfeeder that is yieldably mounted to permit the passage of the plunger,and further to so arrange the feeder that the weight of the operator orman in control of the feeding may be utilized in holding the feeder downin proper position.

A still further object of the invention is to provide a novel form oftension mechanism for adjusting the cross sectional area of the balingchamber in order to retard the movement of the bale.

A still further object of the invention is to provide a novel form ofplunger and plunger returning mechanism.

With these and other objects in view, as will more fully hereinafterappear, the invention consists in certain novel features of constructionand arrangement of parts, hereinafter fully described, illustrated inthe accompanying drawings, and particularly pointed out in the appendedclaims, it being understood that various changes in the form,proportions, size and minor details of the structure may be made withoutdepartingfrom the spirit or sacrificing any of the advantages of theinvention.

In the accompanying drawings z-Figure 1 is a side elevation, partly insection, of a baling press constructed in accordance with the invention. Fig. 2 is a plan View of the same. Fig. 3 is atransverse'sectional view of the press looking in the direction of thehopper, on the line 3 3 of Fig. 1. Fig. 4is a transverse section throughthe press box on the line 4-4 of Fig. 1. Fig. 5 is a detail perspectiveview of the folder or cutter bar, detached. Fig. 6 is a transversesectional view through a portion of the machine at the power head end ofthe machine. Fig. 7 is a sectional plan view ofa portion of the powerhead end of the machine. Fig. 8 is a transverse sectional view drawn toan enlarged scale, illustrating the guide for the thrust bar and thechain guiding rollers. Fig. 9 is a detail view of the whippingmechanism.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

The baling press shown in the drawing is of the portable type, its mainsill 10 being mounted on wheeled axles 11, the forward aXle beingpreferably provided with a king pin connection in order to permit theproper guiding of the machine toward and rom the field of operation. Themain sill 1() is preferably formed of two sections, united by suitablebolts 12, and the sill structure is strengthened by a pair of truss bars13 the intermediate portions of which bear under transversely disposedblocks 14 carried by the sill. The truss bars are preferably formed ofsections having right and left hand screw threads which are connected byturn buckles 15 to permit of the necessary adjustment. The balingchamber 16 is located at one end of the sill, the sill being used as thebottom of the baling chamber, and the sides being IOO IIO

formed of spaced slats 17 which are supported by suitable uprights 18.

Pivoted on pins 19 carried by one of the uprights is a tension board 2()which forms the top of the baling chamber and which may be thrust downby means of a cross bar 21 in order to exercise more or less resistanceto the passage of the bale. This bar 21 is provided with openings forthepassage of cranked rods 23 having operating handles 24 and providedwith rigid collars 25 which bear against the upper face of the bar 21.The lower ends of the rods 23 pass through openings in a cross bar 26below the main sill 10 and enter stationary metallic nuts 27, and as the.lower Il ends of said rods are threaded, the turning of the handleswill either increase or decrease the cross sectional area of the balingchamberand exercise more or less resistance to the passage of the bale.

At the entrance end of the baling chamber is a hopper 29 havingconvergent walls'of the ,i usual type, and the hay or other material fedinto the hopper is acted upon by the plunger head 30 and forced into thebaling chamber proper, the successive charges of material being retainedin place by spring fingers 31 that are secured to the sides of thebaling chamber and project inward therefrom, these fingers engaging andholding the charges of hay or other material that are forced into thechamber by the action of the plunger.

In order to insure the introduction of the full charge of the hoppersection into the baling chamber and to prevent the passage of any of thematerial over the top of the tension board 20, said board carries afolder or feeder 34. This folder or feeder is in the form of a barhaving a curved lower face and of a length equal to the width of thehopper chamber. To the opposite ends of the feeder or folder are securedstraps 35, preferably formed of spring metal, and these spring metalstraps are secured to the tension board. Normally the curved lower edgeof the folder 34 is in a horizontal plane below the top of the plunger30, and as the latter moved forward, the hay or other material will becrowded down under the folder and then as the plunger come forward thefolder will be raised slightly, so that all of the material will enterunder the tension board. ln order to increase the downward pressure onthe folder 34, the spring strips 35 carry a foot board 37 on which theoperator in charge of the feeding may stand.

The plunger is carried by a plunger rod 40 that is held in a centralposition by a number of guides 41 engaging its opposite sides, Vitsupper and lower faces, and near the outer end of the plunger is secureda bracket 42 carrying a roller 43 arranged to run on the sill 10 for thepurpose of supporting said plunger rod.

The plunger receives movement during the head 54.

over guiding sheaves 47, 48 and 49 and is at-I tached at its oppositeend to the plunger. The sheave 47 is carried by a diagonally arrangedbar 50 which is secured across the outer end of the hopper section andserves, also, as a strengthening brace for the hopper.

At the power head end of the machine is secured a plank 50 which, inconnection with the sill 10, serves to support a pair of transversesills 51, and these transverse sills serve as supports for a pair ofcross bars 52 which are arranged to form an upper journal bearing forthe revoluble shaft 53 of the power The lower end of the shaft 53 ispreferablytapered and 1s stepped in a bearing 55 that is carried by thesill 10, and plank 50, the bearing being preferably made lin two partsto permit such adjustment as may be necessary to compensate for wear.That sill 51 nearest the baling chamber is provided with a recess forthe passage of a thrust bar 57, and the sill is strengthened by ametallic brace 58, as shown in Fig. 6.

The power head includes a pair of diamet rically opposed arms which areprovided at their outer ends with anti-friction rollers 61 that areadapted to successively engage with the adjacent end of the thrust bar57, and this end of the thrust bar is preferably provided with astrengthening or reinforcing cap 62 which may be renewed when Worn.Secured to the cap is a pinV 63 which extends through an arcuate slot 64that is struck from the axis of the shaft 53. This slot extends througha plank 65 that is secured to the bracing strap 58, `of each of thetransverse sills, and preferably is supported a slight distance abovethe main sill 10. The pin and groove serve to maintain the heel end ofthe thrust bar in proper position with respect to the anti-frictionrollers of the power head, and the latter will successively engage withsaid thrust bar and carry the same from one end of the slot to theother, the thrust bar being restored to its initial position after eachoperation by the weight 45 through the connections hereinafterdescribed.

To the top of the shaft 53 at a point above the cross bars 52 is secureda two arm lever 67. To one arm of this lever' is secured a sweep 68, theouter end of the sweep being connected to the opposite arm of the leverby a tension rod 69. The outer end of the rod 69 passes through anopening formed in the sweep and is provided with an eye 70 to which thedraft animal may be attached, and

IOO

IIO

the opposite end of said rod passes through an eye formed in the lug 71and carries a nut 72 by which the rod may be adjusted in order toproperly brace the sweep.

Secured to the sill 10 at a point adjacent to one of the transversesills is a transversely disposed bar 75, the ends of which extend aconsiderable distance beyond the sides oi' the sill and are braced bybars 76. To the bar 75 is pivoted a pair of levers 77, the otter ends ofwhich are pivoted to levers 7 8, and these in turn are pivoted to lugsprojecting from the bracket 42 of the plunger rod, the mechanismconstituting a double toggle lever through which movement is imparted tothe plunger rod during the compression stroke.

Secured to the sill 10 is a pair of spaced l bars which are` connectedby .slightly rounded vertical bars 81, the space between these barsforming a guide for the outer end of the thrust bar. The bars 80 carrypins 84 on which aremounted sheaves 85, and these sheaves serve asguides for chains 86. One end of each chain is extended to a pointadjacent to the end of the thrust bar, and is connected to an equalizingbar S7 that is pivoted on a pin S8 carried by said thrust bar, theequalizing bar swinging ireely on its pivot in order that equal Jforcemay be transmitted to each of the levers without regard pp the varyingangular position of the thrust The two levers 77 of the toggles aresurrounded by yokes 90, and each yoke carries an anti-friction roller 91that bears against the rear side of the lever. The forward end of eachyoke is connected to a chain 86, and during the operation of the thrustrod, movement will be transmitted through the chains to these yokes, andfrom thence to the levers 77 of the toggle, the yokes travelling alongthe length of the levers during the operation as the angular position ofthe lever to the line of the pull of the chain varies, and there is thusan automatic adjusting of the point of application of the power to thetoggles during the compression movement of the plunger.

During the compression movement of the plunger, the turning of the powerhead from the sweep will bring the anti-friction roller 61 of the twoarmed lever 60 into engagement with the heel end oi the thrust bar, andthe' latter will be moved in the direction of the baling chamber. Duringthe beginning of this movement, the yokes will be some distance from.the point of connection of the toggle levers 77 and 7S, but as 4theoperation continues, the yokes will automatically move nearer and nearerto this point of connection as the line oi pull of the chain and theangles oi' the levers 77 vary, so that the pull will be exerted at apoint which constantly increases in distance from the iixed pivots ofthe lever 77, thus increasing the leverage force and the power which isexerted upon the toggle leposed toggles, each connected at one ver, andthis increase in force takes place principally during the latter part ofthe compression movement when the resistance oi the hay is increased. Atthe same time as *the angular relation of the operating arm oi' thepower head and the thrust bar grows more obtuse, the power exerted willbe materially increased toward the latter end of the stroke. After eachroller 61 leaves the heel end of the thrust bar, the plunger is drawnback to its initial position by the weight45, and the movement of theplunger head is transmitted through the plunger rod and the togglelevers to the chains, and from hence to the thrust bar, so that thelatter, also, is restored to initial position in readiness to be engagedby the next roller of the power head.

The sweep is provided with an opening for the passage of a pin 95 whichcarries a sheave 96, and a whip socket 97, the latter being preferablyin-the form of a suitable clamp for holding the whip x. Around thesheave extends a cord or cable 99 which is connected at one end to aneye 100 on the sweep by means of a helical tension spring 101. The cordis guided around a sheave 102 near the power head end of the sweep, andthence passes through an eye in a bracket 103 and runs between a pair ofguiding rollers 105 that are carried by a standard 106 to the hopper.rl`he whip is thus placed under the control of the attendant stationedat the hopper and may be used as required. It will be noted by reversingthe direction in which the cord is coiled on the sheave 96 the Whip maybe caused to operate either on the right or the left.
